Solar storage built to last: Trojan SSIG 06 235
Why You'll Love The Trojan SSIG 06 235
-
Purpose-built for solar, not adapted for it. Trojan engineered the SSIG 06 235 specifically for solar, off-grid, grid-tied and unstable-grid systems, so it's designed around the daily charge-and-discharge rhythm your panels actually create.
-
Made for harsh conditions. The Polyon™ ultra-rugged case resists damage from tough environments and guards against acid leaks, and it operates from -4°F right up to 113°F — so a baking shed or a hard winter won't faze it.
-
Long life from proven internals. Maxguard® XL separators and the Alpha Plus® paste formulation are built for long service life and lower overall maintenance costs, which is what really keeps your cost-per-year down.
-
Easier to handle and build with. At 58 lbs it's far more manageable than larger L16 cells, so wiring four for 24V or eight for 48V is a job you can actually do yourself.
Your life, with the Trojan SSIG 06 235
Off-grid power comes down to one quiet question: will the bank still be there in five years?
The Trojan SSIG 06 235 is built to answer it. Trojan designed this battery for solar, off-grid and unstable-grid systems specifically, so it's made for exactly the cycle your panels put it through — charge through the day, draw down through the evening, and repeat.
At 58 lbs per battery, building your bank stays a manageable job rather than a two-person ordeal. Wire four together for 24V, eight for 48V, and each one contributes 1.42 kWh of storage working quietly in the background.
It's the internals that decide how long a bank really lasts.
Maxguard® XL separators and Trojan's Alpha Plus® paste formulation are engineered for long service life, with the paste chemistry optimised specifically for deep cycle operation. The Polyon™ case is built to take knocks and resist the acid leaks that shorten a battery's life, and flame arrestors are fitted as standard. The battery is also 99% recyclable at the end of its working life.
This is a flooded battery, so it does ask something of you: proper ventilation, and regular checks and topping up of the cells. If you're running a larger bank, Trojan's optional HydroLink single-point watering system makes that job considerably faster.
The Trojan SSIG 06 235 in a nutshell:
-
235Ah at the 100-hour rate (214Ah at 20-hour) — 1.42 kWh of storage per battery for solar and off-grid banks.
-
Polyon™ rugged case with flame arrestors — built to survive harsh environments and guard against acid leaks.
-
Wide -4°F to 113°F operating range — dependable through cold winters and hot summers alike.
-
Embedded Low Profile Terminals (ELPT) — clean, low-profile connections with 5/16"-18 stainless steel hardware.

Trojan SSIG 06 235 documents and materials
Disclaimer: The information on this page is provided for general guidance only and should not be taken as professional, electrical or medical advice. The Trojan SSIG 06 235 is a vented flooded lead-acid battery weighing 58 lbs. It contains sulfuric acid and can release hydrogen gas while charging — Trojan advises that batteries must not be installed or charged in a sealed or non-ventilated compartment. Water the cells and set your charger strictly in line with Trojan's data sheet and your local codes, as constant under- or over-charging will shorten battery life. Always use appropriate personal protective equipment, and consult a qualified electrician if you are unsure.
